SSP 7.1 • Introduction 1

SSP 7.1 Features

Advanced control and conﬁguration — The SSP 7.1 Setup and Control Software provides additional conﬁguration options beyond those available through front panel control.

Emulate and Live modes for conﬁguration — The control program can be used in

Emulate mode to create an SSP 7.1 conguration. The modications can be saved and

applied to the unit when a connection is established. In Live mode, the changes are made directly to the unit.

Four digital audio inputs — The unit accepts four digital inputs through two optical (TOSLINK®) digital inputs and two S/PDIF coaxial (RCA) digital inputs.

One analog input — The unit accepts one balanced/unbalanced analog input on a 5-pole

captive screw connector.

Conﬁgurable analog input — Input 5 accepts balanced or unbalanced stereo analog

inputs and can be conﬁgured to accept one or two balanced or unbalanced mono inputs through a captive screw connector. The mono source can be left, right, or a mix summed of the two.

Automatic surround sound format detection and decoding — The SSP 7.1

automatically detects the format of the incoming audio signal, and then applies the userdeﬁned decoding so that signals are sent to the appropriate outputs.

Input source surround sound format indicator — The appropriate LED indicator

illuminates to indicate the incoming format of the selected input source, whether Dolby Digital, DTS, PCM, or two-channel analog.

Dolby Digital and DTS playback — The unit is able to decode and process source format from Dolby Digital and DTS, in their originally encoded formats.

Matrix decoding — The surround sound processor can decode stereo signals to produce multichannel output.

Downmix multichannel source formats — Downmixing produces a mixed stereo or mono channel with an additional option to redistribute the downmixed signal to all channels.

Front panel audio level adjustment with LED level and analog clip indication — Provides overall output volume adjustment for all outputs as well as adjustment of input

level for the analog input. Accompanying LEDs display input gain level, and a dedicated LED

indicator illuminates red when analog clipping has occurred.

Multiple listening modes — Not all listening modes are compatible with certain input signals. The listening mode depends not only on the format of the source material but also on the speaker conﬁguration of the setting. Only those listening modes that are compatible

for a given input are available for that signal. The SSP 7.1 comes with factory default

listening modes that have been matched to the source format to take into account source format and speaker conﬁguration.

Listening mode override — Listening mode override customizes the listening mode to the needs of the source format, speaker conﬁguration, the venue, and the personal preferences

of the listener. Selections made through the front panel can be further rened by the SSP 7.1

Setup and Control Software.

This feature can be used to associate a speciﬁc listening mode with each input type, allowing the user to switch quickly to the listening mode that suits each input type for a given room conﬁguration and the individual user preferences.

SSP 7.1 • Introduction 2

Test signals for setup and calibration — The SSP 7.1 generates test signals, including

band-limited Dolby noise and full-bandwidth pink noise, to facilitate calibration of sound pressure levels from all speakers, and to ﬁne-tune the interaction of a speaker with the

acoustical environment. The SSP 7.1 also offers the option to use an external source for test

signals, which can then be directed to any speaker, or all speakers in sequence.

Speaker compensation delay — The signal to each output channel can be individually delayed so that the sound from all speakers is synchronized when it reaches the listener.

Lip sync offset — This feature delays an audio signal so that it is resynchronized with a video signal that has been delayed by video processing. The offset can be applied to each input channel independently.

Equalization — Nine bands of parametric EQ are available to enhance tone, compensate

for differences in individual speaker output, and adjust frequency response for a given acoustic environment.

SSP 7.1 • Features 4

NOTES: • The length of the exposed wires in the stripping process is critical. The

OUTPUTS

RS-232

ideal length is 3/16 inches (5 mm). Any longer and the exposed wires may

touch, causing a short circuit between them. Any shorter and the wires can be easily pulled out even if tightly fastened by the captive screws.

• Do not tin the wires. Tinned wire does not hold its shape and can become

loose over time.

For more information about input formats, see “Front Panel Features and

Operations” on page 6 and the “Source Formats” section on page 61.

Figure 3. Audio Outputs

Individual output settings are configured through the SSP 7.1 Setup and Control

Software (see page 30) or SIS commands (see page 86):

Mono — Output is through the center channel only but can be reconfigured to be

output through the left and right front channels. In the absence of a center channel, mono is also output through the left and right front channels.

2-channel (stereo) — Only the front left and front right channels are used.

2.0 to 2.1 surround configurations — Audio is output through front left and front

right channels with (2.1) or without (2.0) a subwoofer.

3.0 to 3.1 surround configurations — Audio is output through front left, front right,

and center channels with (3.1) or without (3.0) a subwoofer.

4.0 to 5.1 surround configurations — Audio is output through a combination of front left and right, left and right surround, center and subwoofer channels.

6.0 to 6.1 surround configurations — Adds a back channel to 5.0 or 5.1

configurations. The back left channel receives the sixth channel information and serves as the center back speaker in this configuration.

7.0 to 7.1 surround configurations — Both the back left and right channels are active. Listening modes designed for 6.1 channel outputs pass the same signal to both the back left and right channels. Listening modes designed for 7.1 channel outputs pass

separate signals to each channel to produce a stereo back sound effect.

For more information about speaker configuration and output formats, see the

“Listening Mode Options and Usage” section on page 66.

d RS-232 port — The SSP 7.1 can be congured using the SSP 7.1 Setup and Control

Software or SIS commands, using this 3-pole captive screw connector (or the 2.5 mm

Tip Ring Sleeve (TRS) mini jack plug on the front panel). For more information about the SSP 7.1 Setup and Control Software, see

Source Format

f Input source format indicator — The bank of four LEDs identify the format of the

audio input.

z Dolby Digital ( D): Dolby Digital 2/0, Dolby Digital 2/0 Surround, Dolby Digital 5.1,

or Dolby Digital Surround EX.

z DTS: DTS 2-Channel, DTS Digital Surround, DTS 96/24, DTS-ES Matrix 6.1,

DTS 96/24 ES Matrix 6.1, or DTS-ES Discrete 6.1.

z PCM: 2-channel uncompressed digital source format.

NOTES: • A digital signal that does not have a supported sampling rate or is

compressed PCM is considered an unrecognized signal and is muted.

• When a DVD player is paused during playback, the SSP 7.1 may or

may not continue to receive source format information from the

DVD player. Some players continue to send the same source format information in a loop, allowing the SSP 7.1 to retain the previous settings. Other DVD players completely disconnect the signal from the SSP 7.1 (unlocked state), so that the active input blinks as if there is no connection present. The remainder of DVD players change the source

output to PCM without an actual signal being sent (digital silence).

During digital silence, the PCM LED lights but the 2-CH source LED

does not.

z 2-Channel (2-CH):

z Any source coming through analog input 5.

z If a PCM digital signal is present on any of the digital inputs, both the PCM and

the 2-CH LEDs light.

z If a Dolby Digital 2/0 or Dolby Digital 2/0 Surround source is present, both the

D and the 2-CH LEDs light.

z If a DTS 2-Channel source format is present, both the DTS and 2-CH LEDs light.

To understand more about source formats, see page 61.

SSP 7.1 • Features 6

Mode Override Selection

MODE OVERRIDE

g Mode Override selector — The SSP 7.1 has a wide range of listening modes,

although not all listening modes are compatible with every source format. The speaker conﬁguration of the system may further limit which listening mode is available for a source format. Other factors, such as the room layout and listener preferences, may also inﬂuence the listening mode selection.

The SSP 7.1 has default listening modes associated with each source format. The front

panel provides the user with a limited set of Mode Override settings. These can change the listening mode that is associated with a specific combination of source format

and input. The override selections can be further defined using the SSP 7.1 Setup and

Control Software, or SIS commands.

The new, user-defined listening mode continues to be associated with that source format until Mode Override is used, again, to associate a new listening mode with the source format. To select a listening mode:

1. Use the push button to toggle through the available listening

modes. When no mode override is chosen, none of the LEDs

light, indicating that a user-deﬁned listening mode is in use.

Otherwise, one of the four LEDs shows the current selection.

2. Release the button when the desired LED is lit to select that

The mode override selections that are available through the front panel are:

z Downmix (DOWNMIX) — Downmixes any multichannel source format (digital

inputs only). It also downmixes a 2-channel source format, if the listening mode is set to mono.

It is further defined from the Setup and Control Software (see page 48). Options include:

z Stereo, output on left front and right front channels.

z Mono, output to center channel only or to left and right front channels equally.

z Dolby Pro Logic II/IIx ( PL II/IIx) — uses Dolby Pro Logic II or Dolby Pro Logic IIx

surround processing technology.

z Dolby Pro Logic II extends 2-channel sources to output 5.1 channels. It can be

further deﬁned by control software as either Dolby Pro Logic II Movie (default) or Dolby Pro Logic II Music.

z Dolby Pro Logic IIx extends 2-channel sources to output 6.0 to 7.1 channels

(depending on the speaker setup). It can be further deﬁned by control software as either Dolby Pro Logic IIx Movie or Dolby Pro Logic IIx Music.

z Dolby Pro Logic IIx also provides an extended surround option for multichannel

sources such as DTS Digital Surround or Dolby Digital 5.1.

z DTS Neo:6 (DTS NEO:6) — Uses DTS Neo:6 surround processing technology

to extend analog or 2-channel digital source formats (PCM, Dolby Digital 2/0,

Dolby Digital 2/0 Surround, DTS 2-Channel) to output up to 7.1 channels. It

is further deﬁned by control software as either DTS Neo:6 Cinema (default) or DTS Neo:6 Music.

The SSP 7.1 accepts four digital inputs and one analog input (see Rear Panel Features on page 4):

z Inputs 1 and 2 accept digital signals through S/PDIF optical cables. The optical

cable supports TOSLINK or TOSLINK-compatible optical connectors that conform to

IEC-958, S/PDIF standards.

z Inputs 3 and 4 accept digital signals through S/PDIF coaxial cables.

All four digital inputs accept 16-24 bits PCM audio at 32, 44.1, 48, 88.2, and 96 kHz

sample rates. They support Dolby Digital and DTS source formats.

NOTE: For digital inputs, if there is no valid clock signal at the input and no lock is

achieved, the LED associated with the source blinks twice per second.

z Input 5 accepts a balanced or unbalanced analog input through a 5-pin captive

screw connector. The unit can be conﬁgured to accept:

z A stereo signal

z A mono signal from the right channel

z A mono signal from the left channel

z A mixed sum of right and left channels

The input can also be selected using the SSP 7.1 Setup and Control Software (see Input

SSP 7.1 • Features 9

Mute Output

When the mute state is enabled, all channels are muted simultaneously. To toggle between

mute and unmute:

1. Press and hold the active input button (the button next to the LED that is lit).

2. While still holding the active input button, press the Mode Override button.

When the mute state is enabled, the individual LEDs of the Volume Adjustment LED bar light

in sequence from the top down. This scrolling down pattern repeats while the mute state persists.

All channels can also be muted using the SSP 7.1 Setup and Control Software (see Master

Volume and Mute on page 29).

NOTES: • Selecting another input button while the mute function is enabled, disables

the mute function.

• Adjusting the volume control encoder to change the volume (or the analog

input gain) settings while the mute function is enabled, disables the mute function and increases (or decreases) the volume (or gain) from its previous setting.

• If SIS commands have been used to mute a specific channel, muting and

unmuting all channels also unmutes the channel that was specifically muted. It does not remain in its previously muted state.

Complete System Reset

The SSP 7.1 has three levels of System Reset.

Standard system reset — All parameters that can be adjusted by the control program are reset to default.

Factory reset — In addition to resetting all the parameters of the standard system reset, the baud rate for communicating with the computer is also reset.

Complete system reset — In addition to resetting all the parameters of the factory reset, the ﬁrmware is reset to the factory-installed version.

The standard and factory resets are performed using SIS commands (see the System Reset

SIS commands on page 94).

To perform a complete system reset, hold the Mode Override button while shutting off and restoring power.

To adjust input gain, press and hold the Input 5 button,

while turning the rotary encoder.

CLIP

NOTES: • If the gain level is too high, clipping may occur. When clipping occurs, the red

LED above the Input 5 button lights.

• When using Mono or Mono to All listening mode, the left and right signals

are summed (in the digital domain), which can cause a boost in level up to

6 dB. This type of clipping does not cause the clip indicator LED to light but

is audible. If using a mono mode, it is recommended that the input gain be

reduced by 9 dB below clipping to prevent clipping from occurring.

SSP 7.1 • Features 11

The LED bar lights from the bottom up to indicate the current gain level. No LEDs lit indicates no gain (0 dB, or unity gain); all the LEDs lit indicates maximum gain (24 dB).

Figure 9. Subwoofer Placement

NOTES: • To produce a good bass response from the subwoofer, it should be located at

the front of the room, somewhere between either corner and a point about one third of the way along the front wall.

• The output channel used for the Left Back speaker (in 7.1 configurations) is

also used for the Center Back speaker (in 6.1 configurations).

Bass Management

Speaker Size Settings

Low frequency sound is usually better handled by the subwoofer. Bass management creates the subwoofer channel by separating the low frequency information from the satellite

speakers at a user-dened crossover point. This is summed with the Low Frequency Effects (LFE) information encoded in the source format. When no subwoofer is present, subwoofer

content is sent to speakers set to Large (excluding the center speaker).

This feature sets bass management on or off for a particular speaker, deﬁning the frequency range output by that speaker. These settings also enable or disable the subwoofer and set the crossover frequency.

z Left and right front speakers and left and right surround speakers are set in pairs.

z The center speaker is set as an individual speaker. z Back speaker(s) can be set as a single speaker or as a pair of speakers, depending on the

system conﬁguration.

Small — Bass management is on for that speaker. The output to each speaker (other than the subwoofer) is limited to frequencies above the crossover frequency. By default, center

and surround speakers are set to Small.

SSP 7.1 • Setup 15

Large — Bass management is off for that speaker. The full range of audio frequencies from

the audio source is fed through the output of each individual channel. This may be set in the

absence of a subwoofer. By default, front speakers are set to large. When there is no subwoofer, all speakers set to Large (except the center channel) receive the

summed audio from the ﬁltered low frequency signals of speakers set to Small.

None — This mode prevents any signal from being sent to that output channel. It is not an option for front speakers.

One Small Speaker, Two Small Speakers, One Large Speaker, Two Large Speakers, or None (Surround back speakers only) — This mode determines whether the audio output

channels for the back speaker(s) are passed to the left back and right back (in 7.1 setups) or to the center back (in 6.1 setups).

If either of the one speaker options are chosen, the highest possible number of outputs is

6.1 speakers. In this case, the output is directed to the left back channel output. If either of the two speaker options are chosen, the SSP 7.1 is able to output up to 7.1

channels. Source formats with discrete or matrix mixed 6.1 encoded channels output the

surround back channel signal equally to the left and right back channels. Dolby Pro Logic IIx and DTS Neo:6 listening mode options output a stereo signal to the left and right back channels.

NOTE: If the surround speakers have been disabled, the back speaker options are also

disabled.

By default, the back speaker is set to None, which prevents a signal from being output on

the back channel(s).

Subwoofer — This option allows the subwoofer to be enabled or disabled. When the

subwoofer is enabled, the signal contains ﬁltered low frequency signals from speakers set

to Small in addition to the LFE signal from the source format. If the subwoofer is absent or disabled, the LFE signal is mixed with the bass information of all speakers in the system that

are set to Large, except the center speaker.

NOTES: • When the surround and back speakers are set to None, all multichannel input

signal formats are downmixed and output on all remaining channels.

• In addition, in the absence of a center channel, mono signals are output

equally between the front left and front right channels. Multichannel sources are downmixed to all remaining channels, but Mono to All and Stereo to All options are disabled. Choosing Mono listening mode first downmixes the multichannel source and outputs it to the front left and right channels equally as a dual mono signal.

Crossover Frequency — The crossover frequency sets the boundary below which the low frequency signals from designated output channels are incorporated into bass management. Low frequency signals are only taken from speakers that have been set to Small (see ”Speaker Size Settings” on page 15). The bass management signal is passed to the subwoofer (if present) or speakers that have been set to Large (except for the center speakers) if a subwoofer is not present.

The crossover frequency can be adjusted within the range of 40 Hz to 250 Hz, with a default setting of 100 Hz. Speakers set to Small (see “Speaker Size Settings” on page 15) play

only signals above the set frequency.

SSP 7.1 • Setup 16

Speaker Delay Settings

There are two different signal delays that compensate for different needs.

Compensation delay — In a room where speakers are not equidistant from the listener, sound from the closest speaker reaches the listener before sound from the farthest speaker. This feature allows the user to enter the speaker distance value for each speaker output

channel. The application calculates the delay values for the closest speakers, up to 100.0 ms,

so that all audio arrives at a central location (the “sweet spot”) at the same time.

Lip sync offset — Video delays occur due to changes in programming from a source (TV, Cable, Satellite, or DVD player) and also if the video signal has to be processed through

another device between the source and the display. The lip sync offset feature allows the user to delay the audio sent to all output channels so that video and audio output are synchronized.

Since each source may need a different level of compensation, the lip sync offset for each

input is independently adjustable from 0.0 to 100.0 ms. Apply lip sync offset to the audio

until what is heard matches up with what is seen on the display.

To congure these settings using the SSP 7.1 Setup and Control Software, see “Speaker

Delay Tab” on page 32.

Test Signals

Test signals are used during setup to calibrate the level for each channel and to ensure

proper connection between the individual output channels of the SSP 7.1 and the line

level input channels of an audio signal processor, a receiver with built in ampliﬁer, or a stand alone ampliﬁer that powers the loudspeakers.

The three options for test signal source are pink noise, Dolby noise, and an external source.

By default, the test signal is switched off. Pink Noise — Pink noise is a random signal, generated by the SSP 7.1, with all audio

frequencies present. It provides equal energy per octave to provide a ﬂat response over all frequencies. The main purpose of pink noise is to calibrate the interaction of a speaker with its environment.

Dolby Noise — Dolby noise provides a bandpass-ltered noise, centered at 750 Hz with a 12 dB/octave roll off. This signal is also generated by the SSP 7.1 and is used to set speakers

to the same level when calibrating the room.

Active Input — This option requires an external test signal source, such as a signal

generator, played through the selected input source. Generally, this is a device with an analog signal output, with the SSP 7.1 analog input used as the active input.

Signal generators are usually used to test specic decoding mode outputs. When the External Source option is chosen, the speakers that receive the test signal can be specied.

To calibrate speaker output, use any of these test signals with the SSP 7.1 Setup and Control

Software, see Test Signals on page 36.

Output Channel Trim Settings

This control adjusts the output channel trim level for each output channel to match the levels to the unique needs of any listening environment. The level can be adjusted within the

range from -24 dB to +12 dB. The default setting for each speaker is 0 dB. See Output Trim

on page 39 for more information.

SSP 7.1 • Setup 17

Listening Mode Settings

The SSP 7.1 provides a range of settings that rene the sound distribution for each listening

mode, depending on the decoding mode that has been selected.

Dolby Pro Logic II or IIx Music

Dimension control — This feature alters the ratio of L+R to L-R for two-channel input

signals, which adjusts the sound ﬁeld towards the front or towards the back. The available

settings are Front, Neutral, or Back. The default setting is Neutral.

Center width control — Pro Logic decoding produces a single center signal that comes from the center speaker. If there is no center speaker, a “phantom” center image is produced that is split between the right and left speakers.

If right, left, and center speakers are present, center width control allows variable adjustment of the center image so that is heard only from the center speaker, only from the right and left speakers, or from all three speakers in varying degrees.

There are up to eight different settings, with each corresponding to a speciﬁc calculation angle (Φ). When the setting is 0, the sound comes from the center speaker, when the setting is 7, the sound is from the L/R speakers. The default setting is 3.

Control Position Calculation Angle

0 0.0 0.0 Off 1 20.8 -0.6 -12.0 2 28.0 -1.1 -9.6 3 36.0 -1.8 -7.6 4 54.0 -4.6 -4.8 5 62.0 -6.6 -4.1

6 69.2 -9.0 -3.6

7 90.0 Off -3.0

NOTE: The level of the center speaker (C Level) is related to cosine Φ. The level of the

left and right speakers (L/R Level) is related to sine Φ.

Panorama control — This feature extends the center width control, so that all or part of the center image can be heard from the surround speakers for a “wraparound” effect. The feature may be On or Off. The default setting is Off.

C Level (dB) L/R Level (dB)

DTS Neo:6 Music or Cinema

Center image control — The center image control varies the amount of attenuation applied to the left and right channel information of the input source that is used for creating

the output center channel effects. When it is set to 0, the mixed input signal information,

intended for use in creating the center output channel of the DTS Neo:6 listening modes, is ﬁltered back to the front left and right output channels. This creates the effect of spreading

the centralized audio signal across all three front output channels. When this control is set to 10, the matrixed information intended for the center output channel effects is fully

attenuated, allowing the center channel to create a more centralized effect from the front channels.

The default setting for DTS Neo6: Music is 3. The default for DTS Neo6: Cinema is 10.

SSP 7.1 • Setup 18

Dynamic Range Compression Control

This control is available only with Dolby Digital and DTS source formats that have a Dynamic Range Compression ﬂag.

This control adjusts the gain applied to Dolby Digital or DTS listening modes to compress the signal outputs during the decoding process. The three possible settings are None, Minimum, and Maximum. The default setting is None.

Off — The signal is uncompressed and is played with the full original dynamic range.

Minimum — The audio is partially compressed. In this mode, the volume of the loudest

passages is reduced but quieter passages are kept at their original level. This level is recommended for normal listening.

Maximum — The audio is fully compressed. This level is recommended for environments where loud audio is not permitted.

NOTE: DTS source formats have only two states (On and Off) for dynamic range

compression. Therefore, Minimum and Maximum both apply the same dynamic range compression.

SSP 7.1 • Setup 19

Tone Controls

These controls regulate the bass and treble settings for the system. To adjust the bass or treble tone controls, see Tone Controls on page 27.

Bass — The bass control regulates the amount by which low frequency signals are boosted or cut (see ﬁgure below). It is applied to outputs for all speakers, including the subwoofer.

Figure 10. Bass Range

Treble — The treble control regulates the amount by which high frequency signals for all speakers, except the subwoofer, are boosted or cut (see ﬁgure below).

Figure 11. Treble Range

SSP 7.1 • Setup 20

Volume Output

Equalization

This control sets the volume of the audio output through all channels, globally, to either

Variable (the default value) or Fixed. Variable — When the Volume output is set to Variable, the volume can be attenuated using

the front panel knob, the SSP 7.1 Setup and Control Software, or SIS commands.

Fixed — The Fixed option sets the volume to the current attenuation level. Likewise, all the Output Channel Trim levels (see Output Trim on page 39) are ﬁxed at the values they had

immediately before the Volume Output was set to Fixed. When Fixed is selected, the volume cannot be adjusted through the front panel knob, by the

SSP 7.1 Setup and Control Software, or by SIS commands.

Parametric equalization (or parametric “EQ”) allows the control of amplitude of each band,

center frequency (which can be shifted, widened, or narrowed) and bandwidth (which may

be labeled “Q” for Quality). Parametric equalization is used to improve the audio output in a

speciﬁc acoustic environment.

Resonance reduction — Reduces the level at speciﬁc frequencies that are too loud.

Speaker compensation — Compensates for peaks and dips in individual speaker output

response.

Tonal enhancement — Increases the level of frequencies within a broad or narrow range that sound too quiet.

z Left and right front speakers and left and right surround speakers are set in pairs.

z The center speaker is set as an individual speaker. z Back speaker(s) can be set as a single speaker or as a pair of speakers, depending on the

system conﬁguration.

z The subwoofer can be set to Present or None.

Small — Bass management is on (see page 15). Large — Bass management is off (see page 16).

None — No signal is sent to the output for that channel, effectively removing the speaker

from the current conﬁguration. It is not an option for front speakers (see page 16).

One Small Speaker, Two Small Speakers, One Large Speaker, Two Large Speakers, or None (Back speakers only) — These options determine whether the audio

output channels for the back speakers are output to the left back and right back (in 7.1 setups) or to the center back (in 6.1 setups). For more information, see page 16.

Subwoofer — This option allows the subwoofer to be enabled or disabled (see page 16).

Crossover — The crossover frequency sets the boundary below which the low frequency signals from designated output channels are incorporated into bass management (see

The Input and Output information bar is available from all GUI tabs and is described in detail

on pages 28 and 29.

SSP 7.1 • Setup and Control Software 31

Speaker Delay Tab

After completing the Speaker Configuration tab, conﬁgure the Speaker Delay tab.

Figure 20. Speaker Delay Tab

These controls introduce a signal delay for each speaker that has not had its size value set to None. The two main reasons to adjust the signal delay are:

z To compensate for unequal distances between the speakers and the listener, which

causes sound from different speakers to reach the listener at different times.

z To compensate for a lack of coordination between the audio and the accompanying

video signal.

Speaker distance

When speakers are arranged in a room, there is a central

location or “sweet spot” that offers the best listening point.

However, even in that central location, the speakers are not

necessarily all equidistant from the listener and the sound from the closest speaker reaches the listener before the sound from speakers that are further away.

Speaker distance settings delay the signals going to each

individual speaker (from 0 to 100 ms) so that the signals

from all the speakers are synchronized and reach the listener simultaneously. The default setting for each speaker is 0 ms.

Speakers that are not available in the current conguration are not displayed. When the

back surround is set to one speaker, the right back speaker is unavailable and the left back speaker is renamed center back.

SSP 7.1 • Setup and Control Software 32

Extron recommends that the SSP 7.1 Setup and Control Software is used to set speaker

delays, using either of the following methods.

Two person setup

NOTE: Setting up speaker delays is easier with two people. If only one person is

available, the position of the ears of the listener must be marked precisely. A pile of boxes could be used to ensure that the distances are consistently measured to the correct height. Do not try to guess ear positions, as this introduces measurement errors.

1. Pick an ideal central location where all speaker output signals converge.

2. Use a tape measure to measure the distance from each speaker to the convergence

location. Be sure to measure to the same spot from each speaker.

NOTE: Measurements from the speaker must be to the midrange driver in a

three-way speaker or from halfway between the tweeter and the woofer in a two-way speaker. Measurements to the convergence locations must be at ear height.

3. Click on the Feet (ft) or Meters (m) button to select the units and enter the

Speaker Distance values for each speaker (in feet or meters) in the boxes in the SSP 7.1

Setup and Control Software Speaker Delay tab. The up and down (

{) arrows increase

the distance in increments corresponding to steps of 0.1 ms (0.12 feet or 0.03 meters).

The software automatically selects the farthest speaker and calculates the delay time (in milliseconds) for each speaker.

These values are shown in the Calculated Delay box. The current values are shown in blue, changes (yet to be saved) are shown in orange.

Figure 21. Calculated Delay — Values Pending

SSP 7.1 • Setup and Control Software 33

4. Click the Apply button to save the changes. The new values (previously in orange) are

shown in blue as the current values and there are no values displayed in orange.

To retain the original values, click Cancel instead of Apply.

Figure 22. Calculated Delay — Values Applied

NOTE: Users who wish to calculate the delay time for themselves should follow the full

procedure shown on page 94 in “Setting Speaker Delay Settings using SIS

Commands.”

Setup with a Real Time Analyzer (RTA) calibration tool

1. Choose an ideal central location on which all speaker output signals converge.

2. Place the microphone from the RTA at ear level in the convergence location.

3. Play the audio source. This can be an analog source, provided by the RTA.

4. Use the Test Signal Output buttons in the Testing & Output Trim Tab (see page 36) to

select which speakers are tested and the order in which the speakers are tested.

5. Use the RTA to measure the speaker distance (in ms) for each channel.

6. In the SSP 7.1 Setup and Control Software Speaker Delay tab, select the

milliseconds (ms) button and enter the values for each speaker (in ms) into the boxes. The up and down (

{) arrows increase the distance in increments of 0.1 ms.

7. Repeat steps 4 to 6 until the speaker distance has been entered for all available

speakers.

NOTE: The maximum allowable distance for the furthest speaker is 100 ms.

8. Click the Apply button to save the changes. The new values (previously in orange, see

ﬁgure 21) are shown in blue as the current values and there are no values displayed in orange (see ﬁgure 22).

To retain the original values, click Cancel instead of Apply.

SSP 7.1 • Specifications, Parts, and Accessories 34

Lip Sync Offset

Lip sync offset compensates for a lack of coordination between the audio and the accompanying video signal. This frequently occurs if the video signal has undergone complex manipulation that can delay it several milliseconds relative to the audio signal.

Since some sources may require more manipulation than others, the lip sync offset is set for each source individually to synchronize the audio for that source with the corresponding video signal.

Enter the appropriate value in the lip sync

offset box. This delay is added to every available speaker to resynchronize the video and audio signals.

Input and Output information bar

The Input and Output information bar is available from all GUI tabs and is described in detail

on pages 28 and 29.

SSP 7.1 • Specifications, Parts, and Accessories 35

Testing & Output Trim Tab

After the Speaker Delay tab, conﬁgure the Testing & Output Trim tab.

Figure 23. Testing & Output Trim Tab

Several factors can affect the sound level reaching the listener from different speakers. These factors include the distance from the speaker to the listener, slight variations between the

output channels of a single amplier, and variations between the individual speakers. Use

the output trim to set the output level of each individual channel to compensate for all these variations and ensure that the sound level reaching the listener is the same from all speakers.

This tab also provides a test signal utility.

Test signals

Test signals are used during setup to calibrate the level of each channel and to ensure proper connection between the individual

output channels of the SSP 7.1 and the line level input channels

of an audio signal processor, a receiver with built in ampliﬁer, or a stand alone ampliﬁer that powers the loudspeakers.

Selecting test signal source

There are four test signal options (see Test Signals on page 17): Off, Dolby Noise, Pink Noise, or Active Input. They are selected from the mutually exclusive Source Signal Type buttons.

By default, the test signal is Off. The Dolby Noise and Pink Noise test signals are generated by the SSP 7.1.

NOTE: The Active Input selection is normally used with an analog source on input 5.

The output must be set to Mono to All.

SSP 7.1 • Setup and Control Software 36

Set the external source to Mono to All using one of these methods.

Listening Mode Preferences Tab

1. Select the listening mode Preferences tab (see page 45).

2. Select the input channel that is providing the test signal source (1-5).

3. For whatever source format the test signal is using, select Mono to All.

4. Return to the Testing & Output Trim tab and click on Active Input.

Override Preferences Tab

1. Select the Override Preferences tab (see page 48) and select the input source.

2. For selectable mode To All choose the override Mono to All.

3. On the front panel of the SSP 7.1, use the Mode Override button to select To All.

Selecting speakers to be tested

The currently available speakers are displayed in a graphics box. Speakers that are not available are not displayed.

Output Trim

The Output Trim sliders control the audio signal level for each individual channel output.

Only channels that are enabled in the current speaker conguration are available; the others are displayed but cannot be adjusted. Output trim is adjustable from -24 dB to +12 dB. The

current value for each output channel is shown in the text box.

Figure 24. Output Trim

NOTE: The maximum output volume is tied to the output trim. When an output trim

value is higher than 0 dB, the highest possible output volume is reduced by that amount. For example, if the highest output trim for any channel is set to +5 dB, the maximum output volume is -5 dB.

Extron recommends using a Sound Pressure Level (SPL) meter to set the output trim for each

speaker:

1. Set up the SPL meter at the sweet spot in the room.

2. Send a test signal, generated as described in Test Signals on page 36, to each

individual speaker in turn. Extron recommends using the Dolby Noise signal and sending

the signals to the speakers manually.

NOTE: The test signal should have a sound level at least 20 - 30 dB above ambient

levels.

3. Measure and write down the sound pressure for each speaker.

4. To avoid decreasing the maximum output volume (see the note above), Extron

recommends that you use the speaker with the lowest SPL reading as the zero reference point. Then attenuate all the other speakers by the required amount to balance all speakers.

SSP 7.1 • Setup and Control Software 39

In the example below, the SPL readings for five channels are given in column 2. Channel 4 has the lowest reading and is used as the zero reference point. The difference between each speaker and the zero reference is calculated in column 3. This is the adjustment that must be made to the output trim for that channel.

Channel SPL Reading Output Trim Adjustment (dB)

1 75 -1

2 76 -2 3 79 -5

4 74 0

Select the EQ to be adjusted (1-9) by pressing the desired numbered button and deactivating

the corresponding Bypass button. The numbered buttons are a mutually exclusive set (only

one button can be activated at a time). By default all EQs are bypassed.

Figure 27. EQ Band Selection Buttons

SSP 7.1 • Setup and Control Software 41

When an EQ has been selected, it can be adjusted in the graphic box or the text boxes at the

bottom of the screen.

When the bypass is activated for an EQ, the values are saved for future use but do not act on the signal path. When the bypass is deactivated, changes made to that EQ contribute to the composite graph that is displayed. The graph shows how the activated EQs combine to

affect the signal path in the current setup. Right click the EQ number to bring up a context sensitive menu (see gure 27). Select

Reset to return to default values for the currently selected EQ only, or select Reset All to return to default values for all EQs for the selected speaker channel.

Adjust EQ graphically

When an EQ is selected (see “EQ selection” on page 41) the EQ Graph displays a composite curve showing the individual EQ that is being congured with three parameter adjustment

handles. A vertical white line marks the position of the handle (frequency) currently being adjusted.

Click and drag the EQ number (highlighted at the top of the graph) to adjust the horizontal

position of the handle. Click and drag the center handle up or down to adjust the boost or

cut level (in dB). Click either of the outer handles to adjust the bandwidth, expressed as a Q value (frequency

divided by bandwidth). If either of these outer handles moves, the other outer handle moves in the opposite direction to maintain a symmetry about the center handle.

NOTE: When values are altered in the graphics display, the numeric values in the

“Adjust EQ Numerically” section (see next page) are updated to reflect the changes.

In the example below, the adjustment handles for EQ 3 are shown. The selected EQ is

highlighted at the top of the graph.

A mono signal may be input as left channel only, right channel only, or the sum of left and right channels (both channels input identical mono signals). These controls allow the user to decide whether the Left Only, Right Only, or L+R (Sum) summed input becomes the source for the mono decoding mode. The default is L + R (Sum).

Output Channel(s)

These buttons let the user select whether mono signals are output to the center channel (Center Only) or a dual mono signal is sent to the right and left front channels (Front L+R Only). The default is Center Only.

Input and Output information bar

The Input and Output information bar is available from all GUI tabs and is described in detail

on pages 28 and 29.

Drop-down Menus

The menu bar at the top of the window provides additional tools and options. The four top-level headings are File,

Device, Options, and Help (see ﬁgure at right).

File

The File menu options allow you to save changes made to the

conguration of the SSP 7.1, whether you are running the software in Live or Emulate mode. The current conguration can be saved as

an *.esp ﬁle, which can be opened, further modiﬁed, saved, or saved by a different name. The File menu has ﬁve options.

New — If the software is in Emulate mode, you can save the

conﬁguration changes you have made to a new ﬁle by clicking on New. This creates a new ﬁle with the default settings that can be saved in any directory on your network.

Open — Opens an existing le. The current settings of the SSP 7.1 are replaced by the

values in the ﬁle being opened.

Save — If the le that is currently being modied in Emulate mode has already been named

and saved, this option saves any updates to the same ﬁle. Save As — If the le that is currently being modied in Emulate mode has not been

named, this allows you to name the ﬁle, place it in any directory on your network, and save it.

Exit — Clicking on Exit shuts down the program. Changes to the conguration of the SSP 7.1 made in Live mode are saved as they are made.

Exiting the program after a Live mode session, leaves all changes from that session in effect.

To restore all values to factory defaults, select the Reset... option in the Device menu on the following page.

SSP 7.1 • Setup and Control Software 51

Device

The Device menu has eight options.

Connect... (F5) — In Emulate mode, the option

Connect... is available, allowing the user to switch to

Live mode and open a direct connection to the SSP 7.1 unit. You may also use the F5 keyboard button to switch from Emulate to Live. The Connect... option is

not available in Live mode.

Disconnect (F6) — In Live mode, the option Disconnect is available, allowing the user to close the

connection to the SSP 7.1 unit and switch to Emulate

mode. You may also use the F6 keyboard button to

switch from Live to Emulate. The Disconnect option is not available in Emulate mode.

This section provides information about Source Formats and Listening Mode Options

and Usage.

Source Formats

Surround Channel Information

Surround channel information is written in the following format:

A/B.C (For example 3/2.1)

A represents the number of front channels (maximum 3: front right, front left, and center).

If A is 1, the source format has a mono encoded signal for playback through the center

channel. If A is 2, the source format encodes two discrete channels for stereo playback through the front right and front left channels. If A is 3, there is a discrete encoded signal for all three front speakers.

B represents the number of surround channels (maximum 3: surround right, surround left,

and back). If B is 1, the source format has a mono encoded signal for playback as dual mono through the surround right and surround left channels. If B is 2, the source format encodes

two discrete channels for stereo playback through the surround right and surround left

channels. If B is 3, there is a discrete encoded signal for all three speakers, including the back

speaker.

NOTE: There is no “4” option because, while the SSP 7.1 can output up to eight

full bandwidth channels, there are presently no source formats that can pass

digital bit stream audio information containing 7.1 discrete encoded channels through S/PDIF connections, which is the connection type that the SSP 7.1

supports.

C represents the presence or absence of LFE (1 = present; 0 = none or absent). This is the

discrete bass information, normally designated for use with the subwoofer channel, but may be mixed with other channels in the absence of a subwoofer.

3/3.0 6.0

3/3.1 6.1

NOTES: • The minimum allowable configuration of the SSP 7.1 is 2.0 because the left

and right front speakers are always on. In the absence of a center channel,

1/0.0 and 1/0.1 encoded channels are output equally to both front channels.

• 7.0, 7.0 (with no center channel), 7.1, and 7.1 (with no center channel) are

valid output speaker configurations. However, standard DVD audio sources cannot be encoded as 2/4.0, 2/4.1, 3/4.0, or 3/4.1.

• Blu-Ray DVD players output audio from Blu-Ray DVDs, which can carry 7.1

or more discrete encoded channels. However, that audio can be transmitted only via the HDMI output and can be processed only by an AV receiver that supports HDMI connections. The Blu-Ray player should support S/PDIF

connections that output Dolby Digital and DTS multichannel source formats,

which are also embedded in the Blu-Ray DVD and can be used to feed into the SSP 7.1 via a TOSLINK or coaxial connection.

SSP 7.1 • Reference Material 62

Dolby Digital Source Formats ( D)

Inputs 1- 4 only

Dolby Digital 5.1

(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1, or 1/0)

Dolby Digital is a ﬂexible, discrete, digital technology for carrying audio. Dolby Digital is a

5.1-channel surround sound format and is the standard for DVD video.

Dolby Digital features up to ﬁve discrete channels (front center, front left, front right,

surround left, and surround right), which gives it the “5” designation. Each of the channels is full frequency with respect to human hearing (20 Hz to 20k Hz). There is an additional channel reserved for low frequency effects (LFE), which is usually reserved for the subwoofer speaker(s) or other speakers capable of reproducing low frequencies (3 - 120 Hz). This gives the “.1” designation, since the sixth channel is not full frequency.

Although referred to as 5.1, it includes a variety of combinations, including 1.0, 2.0, 2.1,

3.0, 3.1, 4.0, 4.1, 5.0, and 5.1.

Dolby Digital 2/0

(2/0)

Dolby Digital 2/0 is a specic stereo format encoded by Dolby Digital technology. Encoded information is intended primarily for playback by the front left and front right speakers. TV broadcasts or DVD movie commentaries often have audio tracks encoded using this format.

When the SSP 7.1 detects this source format, both the D and 2-CH LEDs are lit.

Dolby Digital 2/0 Surround

(2/0)

Dolby Digital 2/0 Surround is the consumer version of the original Dolby multichannel analog ﬁlm sound format. Left, center, right, and mono surround are matrix-encoded onto two audio tracks. These two tracks can be decoded by Dolby Pro Logic to recreate the original four-channel sound. This source format is typically used for digital television broadcast signals and older, remastered, movies.

When the SSP 7.1 detects this source format, both the D and 2-CH LEDs are lit.

Dolby Digital Surround EX

(3/2.1)

Dolby Digital Surround EX is a commercial format that reproduces the center channel

information through speakers placed directly behind the listener.

The back surround information is matrix-encoded onto the right and left surround channels

of conventional Dolby 5.1 formats. If there is no back channel speaker, the information for

that channel is played through the right and left surround speakers.

SSP 7.1 • Reference Material 63

DTS Source Formats (DTS)

Inputs 1- 4 only

DTS 2-Channel

(2/0)

DTS 2-Channel is a speciﬁc DTS encoded stereo format. Material encoded in this source

format is typically found in DTS-HD Blue Ray DVDs and is primarily intended for playback by the left and right front speakers. When this source format is present, both the DTS and the 2-CH LEDs light.

DTS Digital Surround

(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1, or 1/0)

DTS Digital Surround is a 5.1-channel surround sound format similar to Dolby Digital 5.1. As

with the Dolby format, there are ﬁve full frequency channels (front center, front left, front

right, surround left, and surround right) and an additional LFE channel.

DTS 96/24

(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1 or 1/0)

DTS 96/24, provides high quality audio reproduction of music and movies from DVDs encoded with DTS Digital Surround source format information. The 96 kHz sampling frequency improves on the more typical 48 kHz. All DTS formats have 24 bit depth, which allows more audio information to be stored compared with the normal 16 bit depth.

DTS-ES Matrix 6.1

(3/2.1)

DTS-ES Matrix 6.1 is a 5.1 channel format with the back surround channel matrix-encoded

into the right and left surround channels. This is achieved in much the same way as the front center channel is matrix-encoded into the front left and right channels of the Dolby Pro Logic

format. The back surround channel is not discrete, so this is not a true 6.1 source format.

DTS 96/24 ES Matrix 6.1

(3/2.1)

This mode is similar to DTS-ES Matrix 6.1 but also has DTS 96/24 encoded.

DTS-ES Discrete 6.1

(3/3.1)

DTS-ES Discrete 6.1 has a back surround channel that is discretely encoded into the DTS

bitstream. This format gives better sound spatialization for complete sound localization and sound pans (the movement of a sound source through the sound ﬁeld). This format provides a data ﬂag to signal the decoder that the bitstream contains an extra channel.

Material encoded in the DTS-ES Discrete 6.1 format cannot carry DTS 96/24 information

because of bandwidth limitations as a result of the discretely encoded surround back channel information.

When the SSP 7.1 detects DTS source material with the DTS 96/24 feature, the sampling frequency of the signal is displayed by the SSP 7.1 Setup and Control Software. The SSP 7.1

Setup and Control Software also changes the text associated with the listening modes to reﬂect that DTS 96/24 is being output.

SSP 7.1 • Reference Material 64

PCM Digital Source Format (PCM)

Inputs 1-4 only

Two channel, uncompressed, digital signals are processed through any of the four digital

inputs. The sampling frequency of the digital signal is displayed by the SSP 7.1 Setup and

Listening Mode Options and Usage

Listening Mode Options

Stereo

This mode plays a stereo source in its pure, unprocessed form. It is the default factory setting for any analog signal and any PCM or Dolby Digital 2/0 source coming through the digital inputs.

It can be used to downmix a multichannel source format into a mixed stereo output signal.

Mono

This mode plays mono source material or stereo that has been mixed to a mono form. It can be used to downmix a multichannel source format into a single mixed mono output signal.

The audio can be output to the center channel only or to the front left and front right channels as a dual mono signal.

Two advanced conﬁgurations apply only to mono sources and outputs.

Analog Source (applies to Input 5 only) — If two mono signals are input on input 5

(analog), the user can choose whether the source input for the mono decoding mode is Left Only, Right Only, or L+R (Sum). The default option is L+R (Sum).

Output Channels — This adjustment lets the user select whether mono signals are output to the center channel (Center Only) or a dual mono signal is sent to the right and left front channels (Front L+R Only). The default option is Front L+R Only.

Stereo to All

This mode plays stereo or downmixed stereo sources to all stereo channel output pairs in the system.

If the source is a single analog mono signal and the listening mode is set to Stereo to All, the following conditions apply:

z If the mono source is set to left channel only, the audio is output only to available left

channels in the system.

z If the mono source is set to right channel only, the audio is output only to available right

channels in the system.

z If the mono source is set to L+R (Sum), the audio is distributed evenly as a dual mono

signal to all available stereo pairs.

Mono to All

This mode plays mono or downmixed mono sources to all channel outputs in the system. The mono source (Left Only, Right Only, or L+R (Sum)) can be selected using the

SSP 7.1 Setup and Control Software or SIS commands.

Dolby Digital 5.1

This mode is used with Dolby Digital encoded source formats. It produces up to 5.1 discrete

channels (center, left and right front, left and right surround, and a low frequency effects channel).

SSP 7.1 • Reference Material 66

DTS

This mode is used with DTS Digital Surround encoded source formats. It also produces up

to 5.1 discrete channels (center, left and right front, left and right surround, and a low

frequency effects channel).

This is the default mode for DTS-ES Matrix 6.1 source formats when the system is set up for 3.0 to 5.1. It can be used with this source format to play the audio without the

matrix-encoded back channel information.

DTS 96/24

This mode is used with DTS Digital Surround source formats that have been encoded using

DTS 96/24. It also produces up to 5.1 output channels with audio sampled at 96 kHz at

24 bit depth.

This is also the default listening mode for DTS 96/24 ES Matrix 6.1 source formats for systems with a 3.0 to 5.1 speaker conguration or if the listener wants to play the audio

without the matrix-encoded back channel information.

DTS-ES Matrix

This mode decodes DTS-ES Matrix 6.1 source formats, for use in a 6.0 to 7.1 system. Upon

playback, the additional surround back channel signal is decoded from the surround left and right channels.

The listening mode can also be used with DTS Digital Surround sources where a surround back channel is created through matrix processing.

DTS 96/24 ES Matrix

This mode is similar to DTS 96/24 but is used with DTS-ES Matrix 6.1 source formats. It can also be used to extend DTS 96/24 source formats from 5.1 to 6.1 by creating a surround

back channel using matrix processing.

DTS-ES Discrete

This mode decodes DTS-ES Discrete 6.1 source formats and reproduces all 6.1 channels,

including the center channel information that was recorded independently, using the Digital Discrete system.

Dolby Digital EX

This listening mode decodes source material that was recorded using Dolby Digital

Surround EX technology. It uses matrix mixing to produce extended surround back channel effects, which create 6.1 outputs from 5.1 source formats. When used with 6.1 source

formats, the original back channel information is replaced by a matrix mixed sixth channel.

NOTE: This mode is available only when the SSP 7.1 is set up for 6.1 or 7.1 outputs and

a multichannel Dolby Digital source format is available.

Dolby Pro Logic

This mode decodes source audio that is encoded in two-channel Dolby Surround to provide four-channel playback (center, left, right and mono surrounds). Sources include

videocasettes, DVDs, and TV broadcasts.

Logic steering techniques extend the impact of the sound track over a wider listening area. This listening mode creates a mono surround channel with a high frequency roll off above

7 kHz.

SSP 7.1 • Reference Material 67

Dolby Pro Logic II/IIx Movie or Music

Dolby Pro Logic II builds on Dolby Pro Logic by breaking the mono surround channel into a

pair of stereo surround channels for playback in a 5.1 surround sound setup. This is achieved

by a matrix surround decoder.

Dolby Pro Logic II works only with two-channel source formats that are used in a 5.1

conﬁguration. It is available as Dolby Pro Logic II Movie and Dolby Pro Logic II Music.

Dolby Pro Logic II Movie is used for VCRs, TV broadcasts, and all programs encoded in Dolby

Surround. Dolby Pro Logic II Music is used for any stereo music recordings.

Dolby Pro Logic IIx Movie and Music extend the Dolby Pro Logic II matrix decoding technology to derive up to seven channels from two-channel or multichannel sources, which provides additional outputs for surround back channel effects.

Both the Movie and Music modes produce up to seven full bandwidth matrixed channels.

Music mode has hard back effects (shared across all surround speakers) instead of just the back speakers, which the Movie mode has.

Dolby Pro Logic II/IIx Music mode provides an additional set of commands to tailor the sound to individual listening tastes.

Dimension control

This alters the ratio of L+R to L-R for two-channel input signals. This has the effect of

adjusting the sound ﬁeld towards the front or towards the back, making the sound more or less spacious.

Center Width control

Pro Logic decoding produces a single center signal that comes from the center speaker. If there is no center speaker, a “phantom” center image is produced that is split between the

right and left speakers. Center Width control allows variable adjustment of the center image

so it is heard only from the center speaker, only from the right and left speakers, or from all three speakers in varying degrees.

Panorama control

This extends the Center Width control, so that all or part of the center image can be heard

from the surround speakers for a “wraparound” effect.

Dolby Digital Pro Logic IIx Movie or Music

Both Dolby Digital Pro Logic IIx Movie mode and Dolby Digital Pro Logic IIx Music mode

build on the Dolby Pro Logic IIx matrix mixing technology to create two additional surround

back channels (right and left back) from the original Dolby Digital 5.1 channel information.

The Dolby Digital Pro Logic IIx Movie mode (applied to multichannel sources) uses the same

Dimension, Center Width, and Panorama controls that are available for Dolby Pro Logic IIx

Music mode (applied to stereo sources). For more information, see the section above.

NOTES: • This listening mode is only available when the SSP 7.1 is set up for 6.0 to 7.1

channel outputs and a multichannel Dolby Digital source format is present.

• Dolby Pro Logic IIx Movie and Dolby Digital EX are electronically equivalent

when the system is set up for 6.1.

SSP 7.1 • Reference Material 68

DTS + Dolby Pro Logic IIx Movie or Music

This mode uses Dolby Pro Logic IIx matrix mixing effects to create up to two additional

surround back channel effects from the original 5.1 information of a DTS Digital Surround source format. Both the Movie and Music modes produce up to seven full bandwidth

matrixed channels for right and left back surround.

NOTE: This listening mode is available only when the SSP 7.1 is set up for 6.0 to 7.1

channel outputs and a DTS Digital Surround source format is present.

DTS 96/24 + Dolby Pro Logic IIx Movie or Music

This mode is similar to DTS + Dolby Pro Logic IIx Movie or Music (see above), but is intended

for use with DTS 96/24 source formats.

DTS + Dolby EX

This mode uses Dolby Digital EX matrix mixing surround effects to create an additional surround center back channel from the discrete 5.1 information of a DTS Digital Surround source format to create up to 6.1 channel effects.

NOTE: This listening mode is available only when the SSP 7.1 is set up for 6.1 to 7.1

channel outputs and a DTS Digital Surround source format is present.

DTS 96/24 + Dolby EX

This mode is similar to DTS + Dolby EX (see above), but is intended for use with DTS 96/24

source formats.

DTS Neo:6 Cinema or Music

This mode produces up to seven separate full bandwidth matrix channels from a 2-channel (stereo) audio input.

DTS Neo:6 Cinema assigns the in-phase component of the signal to the center channels and the reversed-phase component to the left and right surround and center back or left and right back channels.

With DTS Neo:6, the left and right front channels bypass the decoder and are played

directly with no loss of sound quality. The signal outputs from the center, right surround, left

surround (for 5.1), the center back (for 6.1), or left and right back (for 7.1) channels. In the

DTS Neo:6 Music or Cinema mode, there is one adjustable control:

Center Image control

The Center Image control varies the amount of attenuation applied to the left and right channel information of the input source that is used for creating the output center channel

effects. When it is set to 0, the mixed input signal information, intended for use in creating

the center output channel of the DTS Neo:6 listening modes, is ﬁltered back to the front left and right output channels. This creates the effect of spreading the centralized audio

signal across all three front output channels. When this control is set to 10, the matrixed

information intended for the front left and front right output channel effects is fully attenuated, allowing the center channel to create a more centralized effect from the front channels.

Introduction to SIS

The SSP 7.1 accepts SIS commands from a host device such as a computer running the HyperTerminal utility or other control system. The host device can be connected to the

3-pin captive screw connector on the rear panel or to the conﬁg port on the front panel.

To connect to the cong port, use the optional Extron 9-pin D female to 2.5 mm TRS

Conﬁguration cable (part number 70-335-01).

The protocol is 38400 baud, 8 data bit, 1 stop bit, and no parity.

NOTES: • The wiring in the RS-232 cables crosses over so that the surround sound

processor Tx connects with the control device Rx and vice versa.

• Both the rear panel RS-232 port and the front panel configuration port can

be used at the same time. Neither has precedence. The SSP 7.1 responds to

commands in the order received.

SIS commands consist of a string (one or more characters per command eld). Unless

otherwise stated, upper and lower case characters may be used interchangeably. Commands

do not require any special characters to begin or end the command string. Each response from the SSP 7.1 ends with a carriage return and a line feed (CR/LF =

end of the response character string.

When the SSP 7.1 is rst switched on, depending on the model, it sends the message:

To adjust Compensation Delays using SIS commands, follow these instructions.

Two Person Setup

NOTE: Setting up speaker delays is easier with two people. If only one person is

available, the position of the listener’s ears must be marked precisely using, for

1. Pick an ideal central location where all speaker output signals converge.

2. Use a tape measure to measure the distance from each speaker to the convergence

3. When the distances to every speaker have been measured accurately, select the speaker

4. Calculate the delay distance for each speaker, where:

example, a pile of boxes. Do not try to guess ear positions, as this introduces measurement errors.

location. Be sure to measure to the same spot from each speaker.

NOTE: Measurements from the speaker should be to the midrange driver in a

three-way speaker or from halfway between the tweeter and the woofer in a two-way speaker. Measurements to the convergence location should be at ear height.

that is farthest from the convergence location and use that distance as a reference value.
